The Week the Coins Left the App and Went to the Web

This was a web week, top to bottom. Not one line of app feature work shipped to a phone — the native side got a single one-line reliability fix and otherwise sat this one out while the marketing companions turned into something closer to content engines. The through-line: take the data and catalog that already live inside LuckyCoin, and use them to build web pages that are useful on their own and quietly point people back to the app.

LuckyCoin on the web: from calculators to a coin-collecting report

The bulk of the week — 20 commits — went into luckycoin-next, and it moved on three fronts.

First, the tools. What used to be a "Melt Value Calculators" hub got rebranded to "Coin Collecting Tools," reorganized into job-based groups with live spot-price chips and per-tool calls to action, and given a card redesign that swaps placeholder art for real coin thumbnails. Underneath the rename is more surface area: a programmatic /melt hub plus 21 individual coin melt-value pages, each generated rather than hand-written. The search on these pages also learned to speak collector — it now handles the tokens, vernacular aliases, and year-awareness that people actually type when they're hunting a specific coin instead of the tidy catalog name.

Second, and the more interesting piece, is a full data report: The State of Coin Collecting 2026. It's built as an original-data asset — the kind of thing other sites link to — and it leans hard on what LuckyCoin already knows. There are per-set rarity reports spanning 381 sets and 20,354 coins in a Numista-style layout, collector counts on every chart, a mintage column, a country filter, and a headline metal-holdings figure of $89.5M. The collection-size section got reframed as a cumulative achievement ladder, set images now sit next to the bars they belong to, and the whole thing got a friendlier UI with interactive charts. There's even a companion analysis of RevenueCat's State-of-Apps patterns — takeaways, chapters, and a letter — which reads like us doing our homework in public.

Third, the conversion wiring that ties it together: free-taste price tables, a mobile install bar, install attribution so we can tell what actually sends people to the store, eBay and sign-in expansion, value-intent page titles, and rich-results markup for the guides. A utility-first homepage with a series finder and a three-tab nav — one tab being a plain Get-the-App button — anchors it.

LuckyFind: fifty states of metal-detecting law

LuckyFind-Web got the other big content drop: a 50-state series on metal-detecting laws, with OG images and a growth plan attached. It's the same playbook as the coin report — make a genuinely useful reference that stands on its own — pointed at a different hobby. At +15,000-odd lines it's mostly generated content, but it's the kind of thing someone actually searches for before they go digging somewhere they shouldn't.

The conversion kit gets a second home

Once the LuckyCoin conversion setup existed, it was worth reusing, so poultrypal-next got a port of it. Small change, but it's the point of building these things as kits rather than one-offs — the next app in the portfolio inherits the plumbing instead of reinventing it. Both LuckyFind and PoultryPal also picked up Search Console verification files for the analytics service account, which is the unglamorous paperwork that makes any of the SEO work measurable.

One line of native code

LuckyCoin-Android's lone commit fixed a send stall by throttling to MailerSend's rate limit and capping per-recipient retries — so whatever the app emails now goes out at a pace the provider will actually accept instead of jamming. Thirteen lines, and the only app-side work all week.

Add it up and the week was about giving two of the apps a front door on the open web: reference content people find on their own, and the conversion path that carries them from a melt-value lookup or a rarity chart into the app itself. The catalog was always sitting there; this week we started making it earn its keep outside the app store.
